Abstract
Recurrent patellofemoral instability (PFJI) can result in significant pain, functional limitations, and surgical failure. A thorough understanding of the reasons for such failures is crucial for developing effective revision strategies. This article offers a comprehensive guide to diagnosing and managing failed patellofemoral stabilization surgery, highlighting the multifactorial nature of PFJI and the importance of avoiding a "one-size-fits-all" approach. It explores common pitfalls, including over-reliance on unreliable metrics and technical errors during ligament reconstruction. The paper details practical surgical techniques, such as medial patellofemoral ligament (MPFL), medial patellotibial ligament (MPTL), and medial quadriceps tendon-femoral ligament (MQTFL) reconstruction, and outlines key considerations for tibial tubercle osteotomy and trochleoplasty. A structured diagnostic pathway is proposed to help identify the root cause of surgical failure and ensure a tailored approach to revision.
期刊介绍：
Sports Medicine and Arthroscopy Review helps physicians digest the large volume of clinical literature in sports medicine and arthroscopy, identify the most important new developments, and apply new information effectively in clinical practice. Each issue is guest-edited by an acknowledged expert and focuses on a single topic or controversy. The Guest Editor invites the leading specialists on the topic to write review articles that highlight the most important advances. This unique format makes the journal more in-depth, authoritative, and practical than most publications in this field. The journal also includes dozens of full-color and black-and-white arthroscopic images and illustrations.
